Carbide Grade Selection
Choose the C.P.T. grade specifically formulated for your application from the following list:
Uncoated Grades
P30
• Carbide grade for carbon and cast
(P20-P30) steels, works well at medium to low
cutting speeds.
Thread Turning Technical Section
Coated Grades
P25C
(P15-P35)
PVD TiN coated grade for treated and
hard alloy steels (25 HRc & up) at
medium to low cutting speeds.
K20
• Carbide grade for non ferrous
(K10-K30) metals, aluminum and cast iron.
MXC
(K10-K20)
(P10-P25)
BMA
(P20-P40)
(K20-K30)
BXC ••
(P30-P50)
(K25-K40)
PVD TiN coated micrograin for free
cutting untreated alloy steels (below 30
HRc), for stainless steels and cast iron.
PVD TiALN coated sub-micrograin grade
for stainless steels and exotic materials
at medium to high cutting speeds.
PVD TiN coated grade for low cutting
speed. Works well with wide range of
stainless steels.
Note: Due to our unique and specialized production techniques, C.P.T. coated inserts
provide superior cutting performance and exceptionally long tool life.

Conversion of Cutting Speed to Rotational Speed
Conversion of a
selected cutting

by the following
formula:

As can be seen from the chart, some Pitch to Diameter combinationsrequire an anvil change. If change is
required, use AE anvils for EX-RH and IN-LH toolholders and AI anvils for IN-RH and EX-LH toolholders.
